Notes to be applied to tables 4.1 and 4.2

• (a) Where adjacent spaces are in the same numerical category and superscript ‘a’ appears, a bulkhead or deck between such spaces need not to be fitted if deemed unnecessary by the Administration of the flag State. For example, in category (12) a bulkhead need not be required between a galley and its annexed pantries provided the pantry bulkhead and decks maintain the integrity of the galley boundaries. A bulkhead is, however, required between a galley and a machinery space even though both spaces are in category (12).

• (b) The ship’s side, to the waterline in the lightest seagoing condition, superstructure and deckhouse sides situated below and adjacent to the life-rafts and evacuation slides may be reduced to ‘A-30’.

• (c) Where public toilets are installed completely within the stairway enclosure, the public toilet bulkhead within the stairway enclosure can be of ‘B’ class integrity.

• (d) Where spaces of categories (6), (7), (8) and (9) are located completely within the outer perimeter of the assembly station, the bulkheads of these spaces are allowed to be of ‘B-0’ class integrity. Control positions for audio, video and light installations may be considered as part of the assembly station.

5. Regulation II-2/B/5: Fire integrity of bulkheads and decks in new ships carrying not more than 36 passengers and existing class B ships carrying more than 36 passengers (R 27)

NEW CLASS B, C, AND D SHIPS CARRYING NOT MORE THAN 36 PASSENGERS AND EXISTING CLASS B SHIPS CARRYING MORE THAN 36 PASSENGERS:

• .1 In addition to complying with the specific provisions for fire integrity of bulkheads and decks mentioned elsewhere in this part, the minimum fire integrity of bulkheads and decks shall be as prescribed in tables 5.1 or 5.1(a), and 5.2 or 5.2(a), as appropriate.

When approving structural precautions for fire protection in new ships, account shall be taken of the risk of heat transfer between heat bridges at intersection points and of where the thermal barring devices terminate.

• .2 The following requirements shall govern application of the tables:

• .1 Tables 5.1 and 5.2 shall apply respectively to the bulkheads and decks separating adjacent spaces.

• .2 For determining the appropriate fire integrity standards to be applied to divisions between adjacent spaces, such spaces are classified according to their fire risk as shown in categories (1) to (11) below. The title of each category is intended to be typical rather than restrictive. The number in parentheses preceding each category refers to the applicable column or row in the tables.

• (1) Control stations:

• — spaces containing emergency sources of power and lighting,

• — wheelhouse and chartroom,

• — spaces containing the ship’s radio equipment,

• — fire-extinguishing rooms, fire control rooms and fire-recording stations,

• — control room for propulsion machinery when located outside the propulsion machinery space,

• — spaces containing centralised fire alarm equipment.

• (2) Corridors:

• — passenger and crew corridors and lobbies.

• (3) Accommodation spaces:

• — spaces as defined in Regulation II-2/A/2, paragraph.10 excluding corridors.

• (4) Stairways:

• — interior stairways, lifts and escalators (other than those wholly contained within the machinery spaces) and enclosures thereto,

• — in this connection, a stairway which is enclosed only at one level shall be regarded as part of the space from which it is not separated by a fire door.

• (5) Service spaces (low risk):

• — lockers and storerooms not having provisions for the storage of flammable liquids and having areas less than 4 m2 and drying rooms and laundries.

• (6) Machinery spaces of category A:

• — spaces as defined in Regulation II-2/A/2, subparagraph.19.1.

• (7) Other machinery spaces:

• — spaces as defined in Regulation II-2/A/2, subparagraph.19.2, excluding machinery spaces of category A.

• (8) Cargo spaces:

• — all spaces used for cargo (including cargo oil tanks) and trunkways and hatchways to such spaces, other than special category spaces.

• (9) Service spaces (high risk):

• — galleys, pantries containing cooking appliances, paint and lamp rooms, lockers and storerooms having areas of 4 m2 or more, spaces for the storage of flammable liquids, and workshops other than those forming part of the machinery spaces.

• (10) Open decks:

• — open deck spaces and enclosed promenades having no fire risk. Air spaces (the space outside superstructures and deckhouses).

• (11) Special category spaces:

• — spaces as defined in Regulation II-2/A/2, paragraph.18.

• .3 In determining the applicable fire integrity standard of a boundary between two spaces within a main vertical zone or horizontal zone which is not protected by an automatic sprinkler system complying with the provisions of Regulation II-2/A/8 or between such zones neither of which is so protected, the higher of the two values given in the tables shall apply.

• .4 In determining the applicable fire integrity standard of a boundary between two spaces within a main vertical zone or horizontal zone which is protected by an automatic sprinkler system complying with the provisions of Regulation II-2/A/8 or between such zones both of which are so protected, the lesser of the two values given in the tables shall apply. Where a sprinklered zone and a non-sprinklered zone meet within accommodation and service spaces, the higher of the two values given in the tables shall apply to the division between the zones.

• .3 Continuous ‘B’ class ceilings or linings, in association with the relevant decks or bulkheads, may be accepted as contributing, wholly or in part, to the required insulation and integrity of a division.

• .4 External boundaries which are required in Regulation II-2/B/1, paragraph.1 to be of steel or other equivalent material may be pierced for the fitting of windows and sidescuttles provided that there is no requirement for such boundaries to have ‘A’ class integrity elsewhere in this part. Similarly, in such boundaries which are not required to have ‘A’ class integrity, doors may be of materials to the satisfaction of the Administration of the flag State.

Notes to be applied to tables 5.1, 5.1(a), 5.2 and 5.2(a), as appropriate:

• (a) For clarification as to which applies, see Regulation II-2/B/3 and Regulation II-2/B/8.

• (b) Where spaces are of the same numerical category and superscript ‘b’ appears, a bulkhead or deck of the rating shown in the tables is only required when the adjacent spaces are for a different purpose, e.g. in category (9). A galley next to a galley does not require a bulkhead but a galley next to a paint room requires an ‘A-0’ bulkhead.

• (c) Bulkheads separating the wheelhouse and chartroom from each other may be ‘B-0’ rating.

• (d) See paragraph.2.3 and.2.4 of this Regulation II-2/B/5.

• (e) For the application of Regulation II-2/B/2, subparagraph.1.2, ‘B-0’ and ‘C’, where appearing in table 5.1 and 5.1(a), shall be read as ‘A-0’.

• (f) Fire insulation need not be fitted if the machinery space in category (7) has little or no fire risk.

• (*) Where an asterisk appears in the tables, the division is required to be of steel or other equivalent material but is not required to be of ‘A’ class standard. In ships, which are constructed on or after 1 January 2003, however, where a deck, except in a category (10) space, is penetrated for the passage of electric cables, pipes and ventilation ducts, such penetration shall be made tight to prevent the passage of flame and smoke. Divisions between control stations (emergency generators) and open decks may have air intake openings without means for closure, unless a fixed gas fire-fighting system is fitted. For the application of subparagraph.1.2. of Regulation II-2/B/2, an asterisk, where appearing in tables 5.2 and 5.2(a), except for categories (8) and (10), shall be read as ‘A-0’.

6. Regulation II-2/B/6: Means of escape (R 28)

NEW CLASS B, C AND D SHIPS AND EXISTING CLASS B SHIPS:

• .1 Stairways and ladders, corridors and doors shall be arranged to provide ready means of escape to the lifeboat and life-raft embarkation deck from all passenger and crew spaces and from spaces in which the crew is normally employed, other than machinery spaces. In particular, the following provisions shall be complied with:

• .1 Below the bulkhead deck, two means of escape, at least one of which shall be independent of watertight doors, shall be provided from each watertight compartment or similarly restricted space or group of spaces. Exceptionally one of the means of escape may be dispensed with, due regard being paid to the nature and location of spaces and to the number of persons who might be normally employed there.

In such a case the sole means of escape shall provide safe escape.

For ships which are constructed on or after 1 January 2003, the abovementioned dispensation may only be given for crew spaces that are entered only occasionally, in which case the required escape route shall be independent of watertight doors.

• .2 Above the bulkhead deck there shall be at least two means of escape from each main vertical zone or similarly restricted space or group of spaces, at least one of which shall give access to a stairway forming a vertical escape.

• .3 If a radiotelegraph station has no direct access to the open deck, two means of escape from or access to such station shall be provided, one of which may be a porthole or window of sufficient size or another means.

• .4 In existing class B ships, a corridor, or part of a corridor from which there is only one route of escape shall not exceed:

• .1 5 metres in length for ships constructed on or after 1 October 1994,

• .2 13 metres in length for ships constructed before 1 October 1994, carrying more than 36 passengers, and

• .3 7 metres in length for ships constructed before 1 October 1994, carrying not more than 36 passengers.

In new class A, B, C and D ships, a corridor, lobby or part of a corridor from which there is only one route of escape shall be prohibited.

Dead-end corridors used in service areas which are necessary for the practical utility of the ship, such as fuel oil stations and athwartship supply corridors, shall be permitted, provided such dead-end corridors are separated from crew accommodation areas and are inaccessible from passenger accommodation areas. A part of a corridor that has a depth not exceeding its width is considered a recess or local extension and is permitted.

NEW CLASS B, C AND D SHIPS CONSTRUCTED BEFORE 1 JANUARY 2003:

• .5 At least one of the means of escape required by paragraphs.1.1 and.1.2 shall consist of a readily accessible enclosed stairway, which shall provide continuous fire shelter from the level of its origin to the appropriate lifeboat and life-raft embarkation decks, or to the uppermost deck if the embarkation deck does not extend to the main vertical zone being considered.

In the latter case, direct access to the embarkation deck by way of external open stairways and passageways shall be provided and shall have emergency lighting in accordance with Regulation III/5, paragraph.3 and slip-free surfaces underfoot. Boundaries facing external open stairways and passageways forming part of an escape route shall be so protected that a fire in any enclosed space behind such boundaries would not impede escape to the embarkation stations.

The widths, number and continuity of escapes shall be as follows:

• .1 Stairways shall not be less than 900 mm in clear width, if reasonable and practicable to the satisfaction of the Member State, but shall in no case be less than 600 mm. Stairways shall be fitted with handrails on each side. The minimum clear width of stairways shall be increased by 10 mm for every one person provided for in excess of 90 persons. The maximum clear width between handrails where stairways are wider than 900 mm shall be 1 800 mm. The total number of persons to be evacuated by such stairways shall be assumed to be two thirds of the crew and the total number of passengers in the areas served by such stairways. The width of the stairways shall at least conform to the standard as given in IMO Resolution A.757(18).

• .2 All stairways sized for more than 90 persons shall be aligned before and after.

• .3 Doorways and corridors and intermediate landings included in means of escape shall be sized in the same manner as stairways.

• .4 Stairways shall not exceed 3,5 metres in vertical rise without the provision of a landing and shall not have an angle of inclination greater than 45°.

• .5 Landings at each deck level shall not be less than 2 m2 in area and shall increase by 1 m2 for every 10 persons provided for in excess of 20 persons but need not exceed 16 m2, except for those landings servicing public spaces having direct access onto the stairway enclosure.

CLASS B, C AND D SHIPS CONSTRUCTED ON OR AFTER 1 JANUARY 2003:

• .5a At least one of the means of escape required in the paragraphs.1.1 and.1.2 shall consist of a readily accessible enclosed stairway, which shall provide continuous fire shelter from the level of its origin to the appropriate lifeboat and life-raft embarkation decks, or to the uppermost weather deck if the embarkation deck does not extend to the main vertical zone being considered.

In the latter case, direct access to the embarkation deck by way of external open stairways and passageways shall be provided and shall have emergency lighting in accordance with Regulation III/5.3 and slip-free surfaces underfoot. Boundaries facing external open stairways and passageways forming part of an escape route and boundaries in such a position that their failure during a fire would impede escape to the embarkation deck shall have fire integrity, including insulation values, in accordance with tables 4.1 to 5.2, as appropriate.

The widths, number and continuity of escapes shall be in accordance with the requirements of the Fire Safety Systems Code.

CLASS B, C AND D SHIPS CONSTRCTED ON OR AFTER 1 JANUARY 2003:

• .6a Protection of access from the stairway enclosures to the lifeboat and life-raft embarkation areas shall be provided either directly or through protected internal routes which have fire integrity and insulation values for stairway enclosures as determined by tables 4.1 to 5.2, as appropriate.

NEW CLASS B, C AND D SHIPS:

• .7 In addition to the emergency lighting required by Regulations II-1/D/3 and III/5.3, the means of escape including stairways and exits, shall be marked by lighting or photoluminescent strip indicators placed not more than 0,3 metres above the deck at all points of the escape route, including angles and intersections. The marking must enable passengers to identify all the routes of escape and readily identify the escape exits. If electric illumination is used, it shall be supplied by the emergency source of power and it shall be so arranged that the failure of any single light or cut in a lighting strip will not result in the marking being ineffective. Additionally, all escape route signs and fire equipment location markings shall be of photoluminescent material or marked by lighting. The Administration of the flag State shall ensure that such lighting or photoluminescent equipment have been evaluated, tested and applied in accordance with the guidelines as given in IMO Resolution A.752(18).

However, for new class B, C and D ships constructed on or after 1 January 2003 the Administration of the Flag State shall ensure that such lighting or photoluminescent equipment has been evaluated, tested and applied in accordance with the Fire Safety Systems Code.

CLASS B, C AND D SHIPS CONSTRUCTED ON OR AFTER 1 JANUARY 2003:

• .8 In ships carrying more than 36 passengers the requirements of paragraph.1.7 of this Regulation II-2/B/6 shall also apply to the crew accommodations.

• .9 Normally locked doors that form part of an escape route.

• .1 Cabin and stateroom doors shall not require keys to unlock them from inside the room.

Neither shall there be any doors along any designated escape route which require keys to unlock them when moving in the direction of escape.

• .2 Escape doors from public spaces that are normally latched shall be fitted with a means of quick release. Such means shall consist of a door-latching mechanism incorporating a device that releases the latch upon the application of a force in the direction of escape flow. Quick release mechanisms shall be designed and installed to the satisfaction of the Administration of the flag State and, in particular:

• .2.1 consist of bars or panels, the actuating portion of which extends across at least one half of the width of the door leaf, at least 760 mm and not more than 1 120 mm above the deck;

• .2.2 cause the door latch to release when a force not exceeding 67 N is applied; and

• .2.3 not be equipped with any locking device, set screw or other arrangement that prevents the release of the latch when pressure is applied to the releasing device.

NEW CLASS B, C AND D AND EXISTING CLASS B SHIPS:

• .2 - .1 In special category spaces the number and disposition of the means of escape both below and above the bulkhead deck shall be to the satisfaction of the Administration of the flag State and, in general, the safety of access to the embarkation deck shall be at least equivalent to that provided under paragraphs.1.1,.1.2,.1.5 and.1.6.

In new class B, C and D ships constructed on or after 1 January 2003, such spaces shall be provided with designated walkways to the means of escape with a breadth of at least 600 mm, and where practicable and reasonable those designated longitudinal walkways shall raise at least 150 mm above the deck surface. The parking arrangements for the vehicles shall maintain the walkways clear at all times.

• .2 One of the escape routes from the machinery spaces where the crew is normally employed shall avoid direct access to any special category space.

• .3 Hoistable drive-up/down ramps to platform decks must not be capable of blocking the approved escape routes when in lowered position.

• .3.1 Two means of escape shall be provided from each machinery space. In particular, the following provisions shall be complied with:

• .1 Where the space is below the bulkhead deck the two means of escape shall consist of either:

• .1 two sets of steel ladders as widely separated as possible, leading to doors in the upper part of the space similarly separated, and from which there is access to the appropriate lifeboat and life-raft embarkation decks. In new ships, one of these ladders shall provide continuous fire shelter from the lower part of the space to a safe position outside the space. In new class B, C and D ships constructed on or after 1 January 2003 that ladder shall be located within a protected enclosure that satisfies Regulation II-2/B/4, category (2) or II-2/B/5, category (4), as appropriate, from the lower part of the space it serves to a safe position outside the space. Self-closing fire doors of the same fire integrity standards shall be fitted in the enclosure. The ladder shall be fixed in such a way that heat is not transferred into the enclosure through non-insulated fixing points. The protected enclosure shall have minimum internal dimensions of at least 800 mm × 800 mm, and shall have emergency lighting provisions; or

• .2 one steel ladder leading to a door in the upper part of the space from which access is provided to the embarkation deck and additionally, in the lower part of the space and in a position well separated from the ladder referred to, a steel door capable of being operated from each side and which provides access to a safe escape route from the lower part of the space to the embarkation deck.

• .2 Where the space is above the bulkhead deck, the two means of escape shall be as widely separated as possible and the doors leading from such means of escape shall be a position from which access is provided to the appropriate lifeboat and life-raft embarkation decks. Where such means of escape require the use of ladders, these shall be of steel.
